Civilization is the progress toward a society of privacy.

... reason accepts no commandments.

Power-lust is a weed that grows only in the vacant lots of an abandoned mind.

Independence is the only gauge of human virtue and value. What a man is and makes of himself; not what he has or hasn’t done for others. There is no substitute for personal dignity.

Did you get your money by fraud? By pandering to men's vices or men's stupidity? By catering to fools, in the hope of getting more than your ability deserves? By lowering your standards? By doing work you despise for purchasers you scorn? If so, then your money will not give you a moment's or a penny's worth of joy. Then all the things you buy will become, not a tribute to you, but a reproach; not an achievement, but a reminder of shame.

Thinking men cannot be ruled; ambitious men do not stagnate.

The man who does not value himself, cannot value anything or anyone.
